Description

Technical Field

[0001] This utility model relates to television transmitting antennas, and more particularly to a television transmitting antenna that is easy to maintain. Background Technology

[0002] A transmitting antenna is an electronic device primarily used to convert electrical signals into electromagnetic waves for transmission to a designated receiver, such as a broadcasting station, satellite, wireless communication network, or radar system. It consists of various components, with common designs including linear antennas, dipoles, directional antennas, parabolic antennas, and array antennas. After receiving electrical signals from a feed source, the antenna converts these electrical signals into electromagnetic waves through a transmitting element. The rotating transmitting element can change the direction of the emitted signal or optimize signal propagation by adjusting polarization.

[0003] However, current television transmitting antennas have some shortcomings. Television antennas are installed at high places, and when maintenance is needed, they need to be removed from the high place, which is quite troublesome. Utility Model Content

[0004] The main objective of this invention is to provide a television transmitting antenna that is easy to maintain, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A convenient-to-maintain television transmitting antenna includes a fixed rod, a folding rod, and an antenna body. The folding rod is movably mounted on the upper end of the fixed rod, and the antenna body is fixedly mounted on the upper end of the folding rod. A lifting sleeve is fitted on the surface of the fixed rod, and fasteners are inserted inside the lifting sleeve and the fixed rod.

[0007] More preferably, a flip shaft is fixedly installed on both sides of the lower end of the folding rod, a gear is fixedly sleeved on the surface of the flip shaft, insertion holes are longitudinally opened at the front and rear of the lower end of the folding rod, and an installation hole is opened at the upper end of the folding rod.

[0008] More preferably, support blocks are fixedly installed on both sides of the upper end of the fixing rod, and limit holes are opened inside the fixing rod near the upper end.

[0009] More preferably, racks are fixedly installed on the upper surface of the lifting sleeve and on both front sides, and limit rods are fixedly installed on the upper surface of the lifting sleeve and near the front and rear. Sleeve holes are opened on both sides of the lifting sleeve, and the fastener passes through the sleeve holes and the limit holes.

[0010] More preferably, the lower end of the folding rod is movably installed between the support blocks, the folding rod is movably connected to the fixed rod through a flipping shaft, and the limiting rod is embedded in the insertion hole.

[0011] More preferably, the rear end of the antenna body is fixedly installed in the mounting hole.

[0012] Compared with the prior art, this utility model proposes a television transmitting antenna that is easy to maintain and has the following beneficial effects:

[0013] In this invention, by setting up a folding rod, a fixing rod, a lifting sleeve, and fasteners in cooperation, when it is necessary to maintain the antenna body, the fasteners are first removed, and then the lifting sleeve is pulled down. After the lifting sleeve descends to a certain height, the rack of the lifting sleeve will mesh with the gear of the folding rod. As the lifting sleeve continues to descend, the folding rod will drive the antenna body to flip downward, thus making it convenient for ground maintenance personnel to maintain the antenna body.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] like Figure 1-4 As shown, a convenient-to-maintain television transmitting antenna includes a fixed rod 3, a folding rod 1, and an antenna body 2. The folding rod 1 is movably installed on the upper end of the fixed rod 3, and the antenna body 2 is fixedly installed on the upper end of the folding rod 1. A lifting sleeve 4 is sleeved on the surface of the fixed rod 3, and fasteners 5 are inserted inside the lifting sleeve 4 and the fixed rod 3. There is a certain friction between the lifting sleeve 4 and the fixed rod 3, which prevents the lifting sleeve 4 from falling under the action of gravity after the fasteners 5 are removed.

[0021] Furthermore, a flip shaft 101 is fixedly installed on both sides of the lower end of the folding rod 1, and a gear 102 is fixedly sleeved on the surface of the flip shaft 101. Insertion holes 103 are longitudinally opened at the front and rear of the lower end of the folding rod 1, and mounting holes 104 are opened at the upper end of the folding rod 1.

[0022] Furthermore, support blocks 301 are fixedly installed on both sides of the upper end of the fixing rod 3, and limit holes 302 are opened inside the fixing rod 3 near the upper end.

[0023] Furthermore, racks 401 are fixedly installed on the upper surface of the lifting sleeve 4 and on both front sides. Limiting rods 402 are fixedly installed on the upper surface of the lifting sleeve 4 and near the front and rear. Sleeve holes 403 are opened on both sides of the lifting sleeve 4. The fastener 5 passes through the sleeve holes 403 and the limiting holes 302. When the lifting sleeve 4 descends to a certain height, the racks 401 of the lifting sleeve 4 will mesh with the gears 102 of the folding rod 1. As the lifting sleeve 4 continues to descend, the folding rod 1 will drive the antenna body 2 to flip downward, thereby facilitating ground maintenance personnel to maintain the antenna body 2.

[0024] Furthermore, the lower end of the folding rod 1 is movably installed between the support blocks 301, and the folding rod 1 is movably connected to the fixed rod 3 through the flip shaft 101. The limiting rod 402 is embedded in the insertion hole 103. The cooperation between the limiting rod 402 and the insertion hole 103 can fix the angle of the folding rod 1.

[0025] Furthermore, the rear end of the antenna body 2 is fixedly installed in the mounting hole 104.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
